Hastelloy C-276 vs Haynes 230
Side-by-side chemical composition and mechanical property comparison.
Overview
Hastelloy C-276
2.4819
The most versatile corrosion-resistant alloy available. Ni-Mo-Cr-W composition resists both oxidizing and reducing environments. Outstanding resistance to pitting, stress corrosion cracking, and wet chlorine gas. Used in chemical processing, flue gas desulfurization, pulp & paper, and waste treatment.
Haynes 230
2.4733
Nickel-chromium-tungsten alloy — THE combustor can material for gas turbines. Outstanding oxidation resistance to 1149°C for prolonged exposure. Excellent long-term thermal stability (no sigma/mu phase after 16000h at 649-870°C). Lower thermal expansion than most high-temp alloys. Lanthanum addition improves oxide scale adherence. Used for gas turbine combustion cans, transition ducts, furnace retorts, and catalyst grids in nitric acid production.
